1-(2-Amino-5-chlorophenyl)-2,2,2-trifluoroethan-1-one

Abstract

In the title compound, C8H5ClF3NO, the F—C—C=O grouping shows a syn conformation [torsion angle = 1.1 (3)°] and an intramolecular N—H...O hydrogen bond generates an S(6) ring. In the crystal, N—H...F and N—H...O hydrogen bonds link the molecules into [010] chains.
